Abstract

A method of keeping global time in a wireless network, the method comprising the steps of: using a first 802.11 chip set to read a Time Synchronization Function (TSF) to provide an initial time base; using an interconnected clock control circuit to read the TSF time directly from the 802.11 chip set and to implement a local clock based on time values read from the TSF function.
